How Often Should You Replace your Toothbrush?

The answer isn’t as simple as you would think. There are many different toothbrushes available and each has a different manufacturer suggestion on the back of the packaging. Here at Rochester Dental Health, we think that changing with each season is a good suggestion. It’s an easy way to remember it’s time for a new brush. You can simply start using a new one on the first day of each season.

If, however, you use an electronic toothbrush, you should follow the manufacturer’s suggestion. Some recommend intervals more than once a season while others are made of high quality materials that will last a full 6 months.

If you have gum disease or have an immune deficiency, you should consider changing even more often. You should also change it after any sickness that you get. If you get over a cold, you should change toothbrushes.

There are studies that show up to 10 million germs that are harbored on a single toothbrush, but luckily, most need moisture to survive. This means that if your brush is air-dried between uses these germs will die naturally and additionally won’t make you sick.

There are ways to sanitize your brush though if you would like:

  • Soak toothbrush in mouthwash. Mouthwash is an antiseptic, which will kill the germs.
  • Soak toothbrush in 50% water / 50% peroxide.
  • Soak toothbrush in alcohol.
  • Soak in boiling water for five to 10 seconds.
  • You can also run it through the dishwasher.
  • Place toothbrush in very sunny location. UV from the sun will kill germs.

You should not microwave your toothbrush though as is could damage the bristles.

It is also very important to get your teeth professionally cleaned every 6 month. This will get rid of most the bacteria in your mouth at least temporarily allowing your mouth to start fresh. We can take care of all these needs here at Rochester Dental Health, our doctor looks forward to giving you some of the toothbrushes that you will need throughout the year.
